On 16 September 1922 the United States Navy was engaged in assisting the evacuation of ethnic Greeks (mostly Christians) from what is now called Turkey.
Wikipedia explicates a bit:
The Greek genocide, part of which is known as the Pontic genocide, was the systematic ethnic cleansing of the Christian Ottoman Greek population from its historic homeland in Asia Minor, central Anatolia, and Pontus during World War I and its aftermath (1914–23). It was instigated by the government of the Ottoman Empire against the Greek population of the Empire and it included massacres, forced deportations involving death marches, summary expulsions, arbitrary executions, and destruction of Christian Orthodox cultural, historical and religious monuments.
Worth noting: when the terrible Burning of Smyrna began, the Ottoman troops had recently occupied the city; the general officer in charge was Mustafa Kemal, called Atatürk, the "Father of Modern Turkey". Non-Turkish residents who survived the fire, and who were not evacuated by the Allies, included Greeks and Armenians who were force-marched to the east, where most perished.
The modern government of Turkey has never acknowledged the Armenian genocide. This sick sister of Europe has attempted to distance itself from acts of the previous government. How can personal involvement in genocidal acts be denied if there was a continuity of the chain of command personnel? The genocidal acts were not instigated by some antique Ottoman rulers, but by the "Young Turks" that became modern Turkey.
As Prime Minister Erdogan steers Turkey ever closer to sharia law, Turkey appears poised to claim its own brand of death-eating Islamism.
